The landscape of UK energy support has shifted. With the launch of the Warm Homes Plan in January 2026, the government has committed a landmark £15 billion to upgrade 5 million homes by 2030. Whether you are a homeowner looking to cut energy bills or a landlord preparing for upcoming EPC regulations, this guide explains the main UK home upgrade grants and funding available.
Universal Support: Grants and Loans for Every Home
The government is moving toward a “universal offer,” making it easier for all households to access clean energy technology regardless of income.
These schemes include heat pump grants, insulation funding, solar incentives, and government-backed loans designed to help households upgrade their homes and reduce energy bills.
The Expanded Boiler Upgrade Scheme (BUS)
The BUS remains the primary tool for switching to low-carbon heating. As of 2026, the choice of technology has expanded:
- £7,500 Grant: For hydronic heat pumps (air-to-water or ground-to-water).
- £5,000 Grant: For biomass boilers in eligible rural properties.
- New £2,500 Grant: Now available for air-to-air heat pumps (which provide both heating and cooling) and heat batteries.
New Low-Interest Consumer Loans
A new £2 billion facility has been established to provide low- and zero-interest loans. These can be used for:
- Solar Panels & Batteries: To drive the “rooftop revolution” and provide immediate bill savings.
- Combined Packages: Homeowners can combine these loans with BUS grants to cover the full upfront cost of a heat pump installation.
The Landlord’s Roadmap to 2030
Private landlords must ensure all tenancies meet EPC Band C by October 1, 2030. Our guide on the new regulations blog post explained this in detail.
Strategic Financial Planning
- The £10,000 Cost Cap: Landlords are required to invest a maximum of £10,000 per property. If the standard isn’t met after this spend, a 10-year exemption can be registered.
- Counting Third-Party Funding: You can count grants (like the Local Grant) toward the £10,000 cap.
- The BUS Exception: Crucially, funding from the Boiler Upgrade Scheme does NOT count toward your £10,000 cap.

How Do I Take Advantage of This?
At Green Home Guide, we know that navigating energy policy can feel a bit like trying to assemble flat-pack furniture without the instructions (or sometimes even with the instructions!). Technically possible, but unnecessarily painful.
Our job is to simplify the retrofit journey for landlords and homeowners by turning complex options into clear, practical decisions. Green Home Guide helps you plan the smartest path forward, not just the quickest one. Get your Green Home Guide for a tailored energy improvement plan for your property.
